利用数据库技术进行海洋水文测量数据综合管理的研究与实现

摘要

Sea hydrologic data is a kind of important basic sea information.Various instruments are used by hydrological survey department according to different tasks,but great difficulties in integrated management of measurement data are brought by the multi data sources.On the basis of intensive research of various data,a management system for measuring data of multi-type hydrological equipment is developed by using Visual C++in the SQL Server platform.This system fully exerts the characteristics of highly structured database,low redundancy and easily extension,which provides a convenient information platform for storage,management and usage of measurement data of multi-type hydrological instruments.%海洋水文数据是重要的海洋基础信息,海洋水文测量部门根据不同工作经常需要采用多种仪器开展工作,这种多类型水文数据源的出现,给测量数据综合管理带来了难度。在深入研究各类数据特点的基础上,在SQLServer平台上利用Visual C＋＋开发了一个多型号水文设备测量数据管理系统。该系统发挥了数据库技术结构化强、冗余度低、易扩充的特点,为多类型水文设备测量数据入库存储、集中管理、综合应用提供了方便易用的信息平台。
